Abstract

La présente invention se rapporte à un procédé de mise en œuvre d'une migration de charge d'une zone commune. Le procédé comprend la sélection du nœud CN cible du message initial parmi les nœuds CN qui n'effectuent pas la migration de charge après réception d'un message initial envoyé par un équipement utilisateur UE ; l'acheminement dudit message initial au nœud CN cible sélectionné. La présente invention porte également sur un système de mise en œuvre d'une migration de charge d'une zone commune qui peut mettre en œuvre la migration de charge d'une zone commune sans le support de l'équipement utilisateur (UE).
